I did a quick test and it looks like 1st place gives the old xp value and 2nd and 3rd place were nerfed pretty hard.

POTD at level 60 gives 583,200 xp with the 50% buff.
FL with second place gives 418,500 xp at level 60. I can only assume 3rd place xp is beyond awful.

This makes POTD the best leveling spot for the majority of the player base. This could pretty easily kill pvp queues again. It's a really dumb decision imo.
